INCANDESC'ENT-IVIANTLE SUPPORT.

SPECIFICATION forming part of Letters Patent No. 660,501, dated October 23, 1900. Application iled December 30, 1899.` Serial No. 742,077. (No model.)

To all whom it may concern:

Be it known that I, THOMAS S. FULLER, a citizen of the United States, residing at Mannington, in the county of Marion and State of Vest Virginia, have invented new and useful Improvements in Incandescent Gas-Lamps, of which the following is a speciiication.

This invention relates to improvements in incandescent gas-lam ps and one object thereof is to provide an improved support for the mantle.

A further object is to provide improved means for sustaining a smoke-hood.

The invention consists in the novel fea? tures of construction and in the combination and arrangement of parts hereinafter fully described and claimed, and illustrated by the accompanying drawings, in which- Figure 1 is an elevation, partly in section, of a lamp provided with my improvements. Fig. 2 is a plan View of Fig. 1. Figs. 3 and 5 are elevations, partly in section, of a lamp provided with my improvements of slightlymodified form. Figs. 1 1. and 6 are plan Views of Figs. 3 and 5, respectively. Fig. 7 is adetail view of a connection between the support and mantle of modified form.

1 is the base ring or body of the lamp-supporting posts 2, and the latter, adjacent their upper ends, carry ring 3, all of usual and well-known construction.

In Figs. 1 and 2, 4 is a mica chimney, supporting at its top the frame or spider 5, with arms 6 resting on the chimney. Frame 5 is apertured centrally and may be threaded to adjustably support vertical rod 7, or other means may be provided for adjustably sustaining the rod. Said rod is provided at its lower end with hook 8, from which mantle 9 is suspended, with its upper threaded end uniting with smoke-hood 10. Frame 5 is shown downwardly bowed or dished,whereby it is maintained automatically in centered position.

Arms 6 of frame 5 are apertured at 6' to pass over posts 2 and rest on frame-ring 3, as shown in Fig. 3, to positively and iixedly support the mantle and canopy when a large or globe chimney (not shown) of ordinary and well-known form is used, which incloses the entire upper framework of the lamp. In this adjustment the frame 5 is shown in inverted position or bowed upward; butit may, if preferred, be used in reverse position.

In Figs. 5 and 6 the lamp-frame is shown provided Withinneror supplemental posts 11, rising Within chimney 12 and carrying stops 13 adjacent their upper ends, with the apertured arms 14 of frame or spider 14 passed over the ends of posts 1l and resting on stops 13. Frame 14 is identical with frame 5, eX- cepting that it is smaller and adapted to iit within the chimney, With the latter in position between the inner and outer posts. This frame 14 supports rod 7 in the same manner as it is supported by frame 5. This last-described form of support is not dependent on the chimney for sustaining means and is not affected by breaking thereof.

Lamps of this character now in general use are each provided with a single mantle-supporting rod or post, which in many cases softens and bends under the intense heat, distorting and-breaking the fragile mantle and frequently shattering the chimney, which in its fall almost always entirely destroys the mantle. With my improvements the mantle-support is sustained at several points upon the sides, and the distorting action of the heat is so equalized that the mantle is maintained permanently centered, and in addition it provides a permanently-centered support for the smoke-hood. I do not restrict myself to the form of mantel-suspension rod here shown nor to its use in connection with a smoke-hood, and while I prefer to have said rod adjustable vertically in the supporting frame or spider this feature may also be omitted. In lieu of said rod frame 5 may be provided with pendent hook 15, from which the mantle is suspended, as in Fig. 7.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a gas-lam p of the character described, the combination of a metallic plate having rigid projecting arms, saidarms being apertured vertically adjacent their extremities, a vertical frame or support including posts adapted to t the arm-apertures, said plate adapted to sustain a pendent mantle, substantially as shown and described.

2. In a gas-lamp of the character described, the combination of a metallic plate having integral projecting arms, said arms being apertured vertically adjacent their eXtremities, a vertical frame or support including posts adapted to t the plate-arm apertures, and a mantle-hanger arranged centrally on the plate, substantially as shown and de scribed.

3. In a gas-lamp of the character described, the combination of a metallic plate having integral projecting arms, a vertical support for the arms, a mantle-hanger depending centrally from the plate, a rod raised from and supported by the plate, and a smoke-A hood on the rod, substantially as shown and described.

4:. In a gas-lam p of the character described, the combination of a metallic plate having integral projecting arms, a vertical support for the plate-arms7 a Vertical rod secured between it-s ends centrally in the plate and at its lower end adapted to sustain a mantle, and a smoke-hood at the upper end of the rod, substantially as shown and described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
